  • What Color Is Your LMS Parachute?

    I’m reblogging and expanding on a comment I left on Jon Mott’s blog post about the demise of Lively, Google’s Second Life clone. He and I and lots of others are interested in the idea of using collections of social web apps to form Personal Learning Environments in “the cloud.” Institutions are showing interest, but with obvious concerns about lack of control. While Jon’s post focused on the need for caution with cloud apps that can be temporary in nature, I think his words of caution can be applied more generally to any app that doesn’t come with clearly marked exits. Usually, these exits come in the form of standards-based content export capabilities. Look for them. Like the Good Housekeeping Seal of Approval, robust import/export is the sign of a good app.

    Now let’s look at this from a marketing perspective. If you are Blackboard, why would you ever allow anyone to export anything useful? If a customers are packing up their content that means they might be leaving. That’s like a crab trap with a big hole at the other end. That is unacceptable.

    If you are Blackboard, you talk about IMS Common Cartridge compliance. But don’t do anything to make it actually happen. Take your time talking about it. Heck, you can even join the IMS Global Learning Consortium. That looks good. But don’t write any code until you absolutely have to. And when you are finally forced to implement CC, don’t give users an exit that works too well. They might use it.

    Anyway, here is my comment from Jon’s blog:

    Seriously, people have been painting themselves into corners ever since the invention of… um… paint. Whether you are talking about cloud-based apps or a Blackboard server nestled safely in your institution’s server farm, you can still wind up stuck… either locked out or locked in. While parts of the cloud will likely blow away, new ones will likely take their place.

    The real question is “Can you get in or out of where you currently are, and can you take your data with you?” Frankly, I would rather take my chances on being locked out of a few cloud apps than locked into a single, proprietary LMS. Interestingly, I’m working with a group on an IMS CC-Blackboard converter that should get around the import/export problem despite Bb’s foot-dragging. Guess where it will live? In the cloud… with all those risky, new-fangled apps. 🙂

  • Links from my AECT seminar: Web2.0 to support teaching and learning

    Thanks to all who participate in this seminar! I hope it was helpful.

    Some great ideas and links were shared today as we discussed the components that make up Web2.0. Here are the presentation slides. Also, here is a link to my class website (wiki) for preservice elementary school teachers: http://lab-inst.usu.edu/groups/inst4010/. Another great place to learn more about Web2.0 in learning is David Wiley’s Blogs, Wikis, and New Media for Learning OpenCourseWare course.

    And here are links to some of the most interesting sites that were shared:

  • CourseFeed + OpenCourseWare = Personal Learning Environment?

    Yesterday I spoke to Jayson and Rich from ClassTop about CourseFeed, their Facebook app that connects users to other course members and course content. This includes a shared “course wall” and “course notes,” which can be posted to and tracked via Facebook. And for students enrolled at institutions with a supported Blackboard content management system, CourseFeed provides additional course notifications from within Facebook. It got me thinking about how something like CourseFeed could be a bridge from traditional OpenCourseWare sites to something even better. I’m imagining a Facebook app that could serve as the hub of a Personal Learning Environment (PLE), the part of your social network where you can track discussions and fresh content on subjects that interest you. CourseFeed is not there yet, but I think they are moving in the right direction.

    For now CourseFeed seems to be mostly about delivering course notifications for Blackboard users directly into Facebook, and the course community seems limited to students enrolled in the Blackboard course. (I tried the CourseFeed demo, but I couldn’t test it further because my own institution’s Blackboard does not yet support it.) Since CourseFeed is currently designed with an emphasis on Blackboard, the course content is not shareable for many of the reasons Jon Mott pointed out in his OpenEd 2008 presentation: Blackboard is closed, impenetrable, rigid, and ephemeral. Currently CourseFeed invitations are limited to students who are enrolled in the same course at the same institution. Others cannot join the course. And if the Blackboard course is removed at the end of the semester, it gets removed on CourseFeed as well. The students no longer have access to that course.  ClassTop has also had to move to an opt-in agreement with Blackboard institutions — meaning they have to seek institutional approval, school-by-school, before CourseFeed can be enabled on that school’s Blackboard server. I understand why they had to do it this way, but it kind of kills the potential for CourseFeed to go viral. With these kinds of restrictions, it is notable that CourseFeed has nearly 21,000 active monthly users.

    Now think about what something like CourseFeed could be if it were designed without all the Blackboard roadblocks. What if ClassTop designed CourseFeed or another app specifically for course content that was already vetted for copyright issues and openly licensed? These courses exist by the thousands on OpenCourseWare (OCW) sites created by prominent institutions all over the world. If CourseFeed were designed as a way to personalize OCW courses, every course could be linked to its own permanent Facebook group. Anyone interested in the course, including students and professors from other institutions, could join and participate in these groups at any time and for as long as they wish. These connections and discussions might ultimately become more valuable to participants than the original course, perhaps even leading to the creation of additional course content or the formation of new OpenCourseWare sites at other institutions. Additional tools and apps could be developed to promote the kind of learning system that Jon Mott described as open, permeable, flexible, permanent, and free.

    I believe more and more students will want to track their favorite subjects and study groups, the same way they keep track of other groups and friends on Facebook. Blackboard will never fill this need because their learning experience is both temporary and unshareable by design. (Yes, I understand why… fair use… blah, blah, blah.) But if CourseFeed directed those same Blackboard students to some recommended, related OpenCourseWare courses, they could form learning goups that would still be there after the course was over — even after graduation, when they are (hopefully) trying to apply some of what they learned. The beauty of it is that the content is already there. Thousands of courses. Any takers?

    Please Note: When I refer to Facebook, I realize that other, similar sites exist internationally, including many successful clones. PLE applications could be build for any number of social networking sites that support community driven application development. Personally, I think Facebook will continue to lead in this space, both in the US and internationally. They have undertaken an excellent community-driven translation effort, which is another area of interest to me.

  • Hurricane information center community forming

    Over the weekend I got involved in a quick Yahoo Pipes project to aggregate Gustav-related volunteering and housing posts from craigslist. We may have escaped the worst from Gustav, but with other hurricanes already threatening, we are trying to stay mobilized to help in other areas. The idea now it to generalize the site into a Hurricane Information Center while still providing information specific to the individual hurricanes. If you are interested, join the Hurricane Information Center community to see what else needs to be done. We can reuse relevant content and add new tools to provide a resource for folks who will again be displaced by Hannah, Ike, and others.

  • Superbrowser: Google Chrome is on its way

    Chrome is coming! Google’s open source browser project, is coming out in Windows beta. This comic by Scott McCloud, creator of the classic Understanding Comics, does a nice job of explaining the technical details. Here is a brief summary:

    Extreme tab makeover: Instead of traditional tabs below the address bar (like Firefox), Chrome puts the tab buttons on the upper side of the window.

    Multi-process design: This is said to use “a bit more memory up front” but it splits up the processing jobs of individual tabs. It’s similar to the design used in operating systems, with multiple processes happening at the same time. One advantage is that an error that would normally cause your whole browser to crash will now only crash that particular tab. Also, when web pages or plug-ins use a lot of memory, you can spot them in Chrome’s task manager.

    Other streamlining:     The browser has an address bar with auto-completion features (I am skeptical here, only because I have never used an implementation of auto-complete that wasn’t annoying). And when you open a new tab, instead of getting a blank page or your homepage, you will see your most visited webpages as 9 screenshot thumbnails. On the side, you will also see a couple of your recent searches and your recently bookmarked pages, as well as recently closed tabs. There are many other features, including a privacy mode, as well as anti-phishing and anti-malware safeguards that keep updating and warn against malicious sites.

    Anyway, I’m excited to check out what I expect will be the next generation of web browsers. It’s nice to see that this is an open source project. It seems Google is betting big on the OSS (open source software) model. I think it will work. And I find it interesting how quietly Google goes about taking over… everything.
